Description

Pulling eye of ball type for extracting power line}

The present invention relates to a ball-type pulling eye for power line drawing, and more specifically, to the street lamp and the left and right side connection fixing ring which is fixed to the rope and the power line front end while wrapping a part of the rotational ball on the outer side of the rotating ball. When the same facility is installed, the power line can be simply fixed while being towed through the protection pipe buried in the ground between the buried pipe in the concrete buried facility and the facility, and it is generated when passing through the buried pipe and underground protection pipe. The present invention relates to a ball-type pulling eye for power line drawing, in which a binding or a rope is not broken due to friction or rotation.

Today, informatization shows that various power lines or wires are installed underground, underwater, and in the air. These power lines or wires may be installed in tens of thousands or thousands of kilometers.

When the wires or power lines are buried underground, they are dug into the ground and buried with soil. When an abnormality occurs in the track, it is very difficult to check and repair and replacement of the power lines or wires is very difficult.

Therefore, in order to compensate for this disadvantage, a communication tunnel is artificially installed underground and a power line is installed in the tunnel (communication port). In this case, the maintenance and replacement of the power line is easy, but there is a problem that the overall construction cost is enormous.

Therefore, in recent years, a method of installing a hollow pipe (Pipe) having a constant diameter in the ground and inserting a cable into the pipe is installed.

Since the pipeline is buried in length from several hundred meters to thousands of kilometers, the pipeline is branched at regular intervals and a pipeline is installed between the manhole and the manhole. In this case, the rope is inserted into the pipeline, and the pipeline is buried underground, and the power line is installed in the pipeline by pulling and connecting the power line to the end of the rope.

For this operation, a drag member for wire laying, called a pulling-a, is installed at the end of the power line, and technology development is actively performed accordingly.

However, such a conventional pooling eye has the following problems. In other words, when pulling the rope connected with the pulling eye to wire the power line to the pipeline, the power line connected to the pulling eye does not withstand the pulling force, there is a frequent departure phenomenon occurs a construction delay phenomenon occurs.

The present invention is to solve the problems as described above, by installing a facility such as a street lamp by having a left and right connection fixing ring that is fixed to the rope and the power line front end portion while rotatably wrapping a part of the rotating ball on the outer side of the rotating ball. At the time of towing the power line through the protective pipe embedded in the ground between the buried pipe and the facility in the concrete buried ground, the power line can be easily fixed while being covered, and friction or rotation generated when passing through the buried pipe and the underground protective pipe The purpose of the present invention is to provide a ball-type pulling eye for pulling out power lines that do not release the bond or break the rope.

In order to achieve the above object, the present invention is a rotating ball sphere;

Rope seating groove which is bilaterally divided into left and right sides and a ring body that rotatably surrounds the pivot ball center side is contacted with each other from the front side to the upper side, and a rope seating groove is formed in which the leading end of the rope is seated in an arc shape in cross section, On the side, a power line seating groove is formed in which an end portion of the power line is seated in an arc shape, and upper and lower insertion grooves extending to the left and right sides are respectively formed at the upper and lower ends of the rope seating groove and the power line seating groove, respectively. Insertion holes and lower insertion grooves of the power line seating grooves are respectively formed with insertion holes into which ropes and power lines are inserted, respectively; left and right connection fixing rings in which left and right anchor bolts are vertically projected to the left and right of the upper and lower insertion grooves;

The left and right anchor holes are respectively formed on an extension line of the left and right anchor bolts, which are inserted into the upper and lower insertion grooves of the left and right connection fixing rings so that the outer surface forms the same trajectory as the outer surface of the left and right connection fixing rings. The nut is inserted into the nut hole is formed, each of the inner surface is characterized in that it has a fastening bar that is in close contact with the rope and the power line is formed in the close contact groove having a semi-circular rubber ring for supporting the rope and the power line. .

As such, the present invention includes a buried pipe in a concrete buried material when installing a facility such as a street lamp by having a left and right connection fixing ring in which a rope and a power line end part are fixed while wrapping a part of the rotating ball in a rotatable manner. Towing the power line through the protective pipe embedded in the ground between the facilities can be easily fixed while the power cable is covered, and the binding is released or the rope is released due to friction or rotation generated when passing through the buried pipe and the underground protective pipe. The effect is not to break.

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
